The Department of State recently discovered thousands of previously unreviewed documents that relate to Hillary Clinton and the Benghazi attack, according to a watchdog group that has been suing the department to release public records from Clintons tenure.

The State Department disclosed the existence of the additional records in a court filing on Friday and asked the judge for further time to search and review the documents.

The watchdog group Judicial Watch has been suing the State Department for years to turn over public records related to Clintons tenure as secretary of state, the Clinton Foundation, the employment arrangements of Clintons top aides, and her response to the Benghazi attack.

According to the State Department, the newly found records are likely to include information relevant to Judicial Watchs requests. Officials said they would need until at least Feb. 1 to review the documents.

After State filed its motion for summary judgment in this case [on November 11, 2015], State located additional sources of documents that originated within the Office of the Secretary that are reasonably likely to contain records responsive to Plaintiffs request, said the State Departments attorneys in a court filing.

A judge ordered the State Department to turn over public records after Judicial Watch filed a lawsuit against the department in September 2013. The case was reopened last year after it was reported that Clintons emails, which were sent over a personal email server, had not been searched.
